Improvements to toilet ventilating systems where air is drawn from an air inlet up into the tank so flush water can be injected into the vent channel keeping it clean and blocking mist from the fan. Air is drawn out of the bowl via an inlet chamber that is separate from the bowl's flush channel. A wall fan is mounted beneath the tank on the right and connects to a hose from a flange beneath the tank while exhausting its air into the stack behind the tank utilizing a special valve installed in the fans housing. The fans valve is placed very close to the fan blades so as to open be a light pressure from the fan and has a rubber fringe around a solid core to maintain a leak proof seal without sticking. The fan can be easily disassembled for cleaning and easily installed in existing construction or replaced with the aid of tightening knobs using turned cams without requiring any painting touch up work.
